Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and 2, a multifunctional joint for venous transfusion comprises a three-way joint 1, wherein the three-way joint 1 comprises a first interface 11 and a second interface 12 which are transversely communicated, and a third interface 13 which is perpendicular to the first interface 11 and the second interface 12, the first interface 11 is used for connecting pipelines such as a medium-length catheter and the like which are left on a patient body, the second interface 12 is used for connecting a venous blood collection tube, the third interface 13 is used for connecting a venous transfusion tube, the third interface 13 is connected with a catheter 2, one end of the catheter 2 passes through the third interface 13 and extends to the side of the second interface 12 to form a bending part 21, the other end of the catheter 2 is connected with a transfusion joint 3, the catheter 2 is located in the side of the second interface 12, and a flow stopping clamp 23 is arranged outside the catheter 2 away from the third interface 13. The second interface 12 is connected with a heparin cap 4, and the infusion connector 3 is a needle-free closed infusion connector.
One end of the conduit 2 passes through the third port 13 and extends to the side of the second port 12 to form a bending part 21 with a length 1/3-2/3 of the length between the third port 13 and the second port 12. The diameter of the conduit 2 is 0.4-0.7 cm. The inner diameter of the second interface 12 is 1-1.5 cm.
The valve 22 is arranged in the catheter 2 on the side of the second connector 12, the flow stopping clamp 23 is arranged outside the catheter 2 far away from the third connector 13, and by adopting the structure, blood can be effectively prevented from flowing into a venous transfusion tube during blood collection. One end of the catheter 2 penetrates through the third port 13 and extends to the side of the second port 12 to form 1/3-2/3 of the length of a bending part 21 which occupies the length between the third port 13 and the second port 12, and by adopting the structure, the valve 22 on the catheter can be prevented from being punctured during blood collection.
